BACKGROUND

1. Field of Invention

This invention relates to five sided, open top, generally leak-proofcontainers being formed from a single substrate, and which require nointeriorly located tab receiving apertures or adhesives or fasteners toachieve or maintain a structural stability of the container in eitherits manufacturing, assembly, or use.

2. Description of Prior Art

Within prior art, the means for achieving or retaining the form andstructural stability of a five sided open top generally leak proofcontainer being formed from a single planar sheet substrate had includedeither adhesives or fasteners or tabs and interiorly located tabreceiving apertures. Those containers which did include tabularappendages that interlocked with tab receiving apertures were nottotally leak proof, as the apertures were usually located approximatelyintermediate the containers height.

Most generally leak proof containers being formed from a single planarsheet substrate which do not utilize interiorly located tab receivingapertures, and which do not require separate fasteners, will require atleast one glued or adhesive taped area within the container, and so allstrengths are totally dependent on the glue or adhesive tape to notbreak down when being saturated by water for long periods.

Water proof glues or adhesive tapes with oil based properties will notadhere to a containers wet surfaces when it needs to be assembled in amoist or rain soaked environment, or when assembled upon a waterssurface.

Other than application Ser. No. 11/288,463, prior art lacked additionalwall strength within at least two oppositely facing walls by notincluding up to four exteriorly located hingedly mated triangular shapeprojections.

Also not found, were two oppositely facing wedge-locked end walls whichexhibit structural wall strength from solid or liquid weight stressloads from within or without the container; and whether upon land in asmall scale for retaining a user's held objects, or either in a largerscale when on a water's surface and when containing the user themself.

Prior art mostly included folded flaps which abut the container's endwalls for forming locking tabs or gluing or stapling. Prior art andincluding application Ser. No. 11/288,463 did not disclose aninterlocking flap being hingedly connected to an end wall and comprisingnarrow notches within the flap which interlock with notches within aside wall as a means for forming and securing a structural stability ofa part-less self securing generally leak-proof container.

Within single substrate five sided open top containers, there is notmuch lateral sidewall stability, and especially in the longer sidewallsof an elongate container, and particularly when the walls are up to tenfeet long.

Prior art and including application Ser. No. 11/288,463 also did notdisclose any alternative embodiments using additional sidewallstrengthening flaps, or double hinged strengthening flaps to furtherstrengthen an extremely elongate containers weakest areas, and which arethe intermediate portions of the two longest walls exterior edges whichmay tend to waiver laterally under pressure.

Prior art did not address or disclose a container retaining its leakproof form when in an almost fully disassembled and nearly planar state;and nor did prior art address or disclose the advantage of a hingedlyconnected interlocking flap to further strengthen an almost fullydis-assembled container by aiding to at least some degree a preventionof lateral twisting at each elongate end of the container.

Prior art did not disclose a manufacturers or users option of usingelastic cords to instantly and partially pre-assemble a part-less selfsecuring container before a final interlocking of a notched, hingedlyconnected end wall interlocking flap within a notch of a side wallsupper perimeter edge.

Prior art did not address or disclose any leak proof container which isable or intended to be assembled upon a waters surface by a swimminghuman user, and without a need for any tabs or interiorly located tabreceiving apertures, or separate fasteners, or adhesives, or glues, ortapes of any kind.

Summarily, there is no prior art of an open top, five sided, leak-proof,part-less, self securing container being formed of a single substrate toform a container for a human user and or their objects havingwedge-locked end walls via hingedly connected end wall flaps toestablish similar end wall strengths as this new concept of a part-lessself securing leak-proof container being formed from one single sheetsubstrate.

SUMMARY

A generally leak proof open top self securing container with end walls(18) having hingedly connected interlocking flaps (20) having narrownotches (22) which interlock with V-shape notches (12), angled notches(13) or circular shape notches (15) located within the edges of the sidewalls (10) to wedge-lock and laterally secure the end walls (18) betweenthe interlocked locations and exteriorly located triangular shapehingedly-mated corner projections (24). A first portion (1) of bendlines parallel the substrate's longest length, and are spaced inwardlyto determine a side walls (10) height. A second portion (2) of bendlines parallel the substrate's shortest length to define the hingedlyconnected interlocking flaps (22). A third portion (3) of bend lines areparallel with and located further inwardly than the second portions (2)to perpendicularly and nearly abut or abut and conjoin the firstportions (1) and so determine the height of an end wall (18). A fourthportion (4) of bend lines extend inwardly and angularly from approximatecorner areas to locations where the first (1) and third (3) portionsnearly abut or abut to define the triangular shape corner projections(24). No fastening parts, or adhesives, or tabs or interiorly locatedtab receiving apertures are required to retain the structural stabilityof the preferred embodiment. One alternative embodiment includes a fifthportion (5) of bend lines extending the width to enable a compactfolding. Other embodiments include a sixth portion (6) of bend lines todefine a hingedly connected side wall strengthening flap (14) to foldback onto the side wall being retained by a notch (22) of theinterlocking flaps (20), and with one embodiment having a spoon orpaddle shape strengthening flap (16) having perforated portions (17)within the bend line (6) for optional removal. A strengthening flap maybe in any shape which adds at least some additional strength. Otherembodiments include closed cell floatation foam (40), flute channelplugs (44) (46) (48), side wall apertures (26), connecting rods (39),portions of an end wall being angled (19) outwardly from the floor, andelastic cords (36). The container may be formed of most any materialwhich is malleable or bendable at least once, and in any sizeappropriate for the manufacturer's intended use.

OBJECTS AND ADVANTAGES

A first object and goal of this invention is to form a self securingleak proof container having five sides and an open top, and whileremaining structurally secure after being quickly assembled, and withouthaving or requiring any interiorly located tabs or tab receivingapertures, or fasteners, or adhesives in either its manufacturing,assembly, or use.

Advantages of the first object include cost effective manufacturing, aquick assembly, and a sturdy structural stability of a generally leakproof container; and pending the substrate chosen according to the enduse purpose.

A second object of this invention is to form a generally leak proofcontainer in multiple sizes and different substrate materials of thepreferred embodiment to contain a human user and or their objects.

Multiple advantages of the second object include a fast assembly of agenerally leak proof container which may be marketed for many end usepurposes including sandwich containers, foot baths, tool trays, foodtrays, emergency flood containers, pet litter boxes, etc. Themultiplicity of end use purposes of this concept of a quick assemblinggenerally leak proof container is understood to be distinct andirrelevant to any claims disclosed; yet is deemed by the writer to beworthwhile to convey to the reader the potential value of this newconcept of a container which requires no fastening parts, or interiorlylocated tab receiving apertures, or adhesives in its manufacturing,assembly or use. Cost savings are obvious.

One additional advantage of the second object is how the structure whenmade of a ½ inch thick substrate; and in a size of 2 foot by 10 footwith 1 foot high side walls is able to support two human users, anelectric battery, a trolling motor under power, and other items totalingwell over 400 pounds while on a waters surface.

A third object of this invention is to wedge-lock an end wall betweenexteriorly located hingedly mated triangular shape projections andlocations of interlocking between notches within the side walls and anend walls notched and hingedly connected interlocking flap, and with theplanar surface of the interlocked flap being angular to the planarsurface of the end wall.

The advantages of the third object is an end wall which cannot laterallywaiver in any direction, and portions of the side walls being adjacentthe location of interlocking which also cannot laterally waiver in anydirection, and portions of the side walls being near the interlockinglocation which still cannot laterally waiver in their elongatedirection; yet will still resist excessive wavering in directionsperpendicular to their elongate length. The difference in angle betweenthe interlocked flap and end wall provides much added strength.

For clarity of explanations; references to any elongate direction shallrefer to a longest length of a container which is not absolutely squarein its dimensions excluding height; and wherein the longest dimensionrefers to the side wall(s) and a shortest dimension refers to an endwall(s). The greatest amount of any lateral wavering of a side wall islocated intermediate the two end walls, while yet still only wavering indirections perpendicular to the elongate length.

A fourth object of this invention within an alternative embodiment is toprovide a reinforced side wall(s); wherein a strengthening flap ishingedly connected to fold back onto the side wall, or angularly to aplanar surface of the side wall, and with the option of the notch of anend wall's interlocking flap retaining a side wall strengthening flapabuttingly or adjacent to the side walls either exteriorly or interiorlyto the containers cavity area.

Advantages of the fourth object providing a strengthened elongate sidewall(s) are easily seen when a container has a cavity area being 26inches wide by 10 feet long, and with 11 inch high side walls, andwherein an intermediate area of the extremely long side walls edges arethe weakest location. When the container is formed of a light weightpaper board or foam plastic, and in a size ratio more proportioned to around sandwich, the side wall strengthening flaps still provideadditional strength in locations intermediate the container's longestdimension. The side wall strengthening flaps provide additionalstrength, and whether angled to the planar surface of the side wall, orwhether abuttingly flush with the side wall.

A fifth object of this invention is to take further advantage of theside wall strengthening flaps by incorporating the shape of a foldingpaddle blade. The folding paddle is listed as U.S. Pat. No. 7,309,364 byWagenknecht, et al filed on Nov. 22, 2006. The strengthening flapswithin any embodiment may be perforated in the hinged bend line fortheir optional removal.

Advantages of the fifth object where the side wall strengthening flapsare in a shape of a removable folding paddle include the ability tostack and store multiple emergency leak proof containers and theirattached means of propulsion in a flat planar form without a need forany tools, parts, fasteners, or adhesives required in the assembly ofeither the container or the serratingly attached strengthening flaps.Stackability and compactness within any product has merit.

An end user who is initially protecting their valuables within a floodsituation may alternatively use the same container as an emergencyescape container while additionally having the option of using thesidewall strengthening flaps as a means of propulsion for the emergencyescape leak proof container.

It is a sixth object of this invention to have a plurality of aperturesnot located interiorly or intermediate a side walls height; but justadjacent a side walls uppermost perimeter edge to not greatly affect theability of the container to remain leak proof. The apertures may becompletely cut out, or partially cut with a portion remaining intact toform a flap which is pushed through by the user to expose the aperture.

Advantages of the sixth object including apertures near a side wallsuppermost perimeter edge provide an end user many options.

After tearing off the serratingly attached sidewall strengthening flapsof this embodiment, the user may then fold the strengthening flaps andthen thread the folded strengthening flaps through the apertures;wherein the apertures will serve as oar lock apertures.

Further advantages of the apertures include an end users option ofthreading a shovels handle, or a similar rod, through two oppositelyfacing apertures, wherein two opposing persons may grip the rod to carryor drag heavy items such as sand for sandbagging around a soon to beflooded home and such.

One end wall of the container may be unlocked and unfolded downward towhere it is flat with the grounds surface for raking sand into thecontainer before re-interlocking the end wall for transport of the sand.When the container has at least 4 apertures, up to 8 persons maysurround the container for carrying extremely heavy loads such as wateror sand. The 4 exteriorly projecting triangular shape flaps may serve assecure hand holds for up to 4 persons, but the rod threaded hand holdswill prevent a container from buckling or twisting in the center area ofthe container when under extreme weight loads.

Further advantages of the sidewall apertures include options of tyingmultiple containers together with ropes or fasteners, or to form a largeraft by threading rods completely through the apertures of two or morecontainers. When the side walls of two containers abut each other, andwhen appropriately sized rods are threaded through the apertures of bothcontainers, the two containers then form at least one dual compartmentcontainer with minimal lateral twisting.

It is a seventh object of this invention to utilize other materialsubstrates in addition to a paperboard or light weight plastic; andwherein an extremely durable and waterproof substrate such as acorrugated polymer plastic may serve as the containers materialsubstrate for containers being larger than a sandwich container.

A thickness of corrugated plastic sheet is measured by its manufacturersaccording to its wall thickness. Two planar walls are conjoined by aplurality of elongate paralleling ribs, and with both walls and ribsbeing generally the same thickness. A 4 mil wall equals an approximate3/16 inch plus thick substrate. A 6 mil wall equals an approximate ¼inch thick substrate. A 10 mil wall equals an approximate ½ inch thicksubstrate.

Corrugated plastic sheets are also available with a lamination of U.S.Coast Guard approved closed cell foam on either one or both sides of thesubstrate. The laminated foam can be anywhere between 1/16 inch to ¼inch thick.

One best advantage of the polypropylene corrugated plastic embodiment iswithin the polypropylene plastics own material properties. The materialswater absorption within 24 hours is described by one major manufactureras being only 0.02%; and with any flute channel being pluggable foradditional floatation.

Yet, the material floats without an absolute need for sealing orplugging any of its elongate flute channel apertures. A heavy movingcurrent may drag an unassembled container slightly downward from thewater's surface, but within a lake or flooded area without fast movingcurrents, the unassembled container will float to the surface for aswimming user to assemble while in the water.

Further advantages of the seventh object include a 160 pound user beingable to forcefully lean back against the described wedge-locked end wallwith both hands in the air, and while the container is on a water'ssurface, and when the container is formed of an appropriate thickness ofcorrugated plastic. Same applied stresses and even more have proven theend wall's wedge-locked strength, and including an electric trollingmotor being under full power, and with no added reinforcements appliedto a 10 mil, ½ inch thick end wall.

Any inward stresses or pressures placed on the end walls in an inwardlydirection toward the container's cavity area have proven equallyresistant to any lateral shift or bending of the wedge-locked end wall.Side wall areas at and near the end wall prove equally resistant to anylateral wavering. Only side wall areas intermediate the length of acontainer may begin to waiver under stress, and yet are much improvedwith the previously described side wall strengthening flaps.

Further advantages involve prototype testing of the corrugated plasticembodiments floatability with a user on the water in a container havinga cavity area of 2 feet by 8 feet, and with both end wall interlockingflaps disengaged. As a user holds both sidewalls and pushes them equallydownward to within an inch of the waters surface, water pressuresexterior to the containers cavity area force the walls upwardly to forma rectangular shaped saucer-like form. As the user pulls both sidewallsinwardly, the end walls shift upwardly while the container regains itsnormal assembled shape, and remains afloat as the user releases one ofthe two sidewalls to reach forward or backward to re-interlock thenotched interlocking flap within the notch of the elongate sidewall.

This advantage of the container still remaining afloat while thecontainer is in an almost planar and unassembled state was discoveredduring one of many proto testings where a first interlocking flap wasaccidentally disengaged, and where the container stayed afloat to allowthe still floating passenger to reach forward to re-engage theinterlocking flap with one hand. Both interlocking flaps were then soondisengaged to further explore the container's floatability in thepreviously described rectangular saucer-like form.

Once the corrugated plastic material is bent at the slit formed hingeline between the interlocking flap and the end wall, residual memorywithin the plastic material tends to keep the bend at least to somedegree. The strengthening difference in planar surface angles betweeneach end wall and its hingedly connected interlocking flap cooperateswith all other side wall pre-bends and adjacently located difference inplanar surface angles, and each corners triangular shape projectionpre-bends and adjacently located difference in planar surface angles,and the users weight load, and the waters surface to maintain thecontainers partially assembled rectangular saucer-like floating form.This difference in angles between each end wall and its hingedlyconnected interlocking flap especially prevents excessive lateraltwisting of the substrate at each elongate end of the elongate partiallyassembled container; and while upon a waters surface.

Summarily, each hingedly attached interlocking flap has multiplestrengthening advantages; and even as the container is almost planar andunassembled. The container will still remain leak proof to contain ahuman user without a full upward erection of the side walls or endwalls, and especially without an absolute requirement of any means ofinterlocking, or any direct interlocking between the interlocking flapsand the notches located within each side wall.

It is an eighth object of this invention to optionally have elasticcords secured at each elongate end of the container. This embodiment mayalso have a closed cell floatation foam material adhered to its surface,or may have closed or filled flute channel apertures, and including onlychannels at one end being plugged to compensate for any water absorbingor non-floating properties of the elastic cords.

Advantages of a corrugated plastic embodiment or most any other materialsubstrate utilizing the elastic cords include a container which isinstantly and partially pre-assembled in seconds. When the substrate isother than a plastic material having memory retention properties in anybends, and when the container is not upon a waters surface, a finalinterlocking of the hingedly connected end wall interlocking flaps willmost likely be required by the user. But when the substrate is of acorrugated plastic or any plastic with at least some memory retentionwithin any hinge bend line areas, and when used as a container upon awaters surface, an interlocking of the interlocking flaps is notrequired, and as previously described concerning the partially assembledrectangular saucer like form. With the elastic cords embodiment, allwalls will be more fully erected upwardly and nearly to a fullyassembled containers position.

It is a ninth object of this invention to have at least one or morehinge bend lines extending the shortest length of the container.

Advantages of the ninth object include the ability of the container tobe folded for storage and transport. This embodiment is disclosed withinU.S. application for patent Ser. No. 12/069,625, and filed Feb. 12, 2008by Wagenknecht, et al.

Combined advantages of the eighth and ninth objects include an emergencycontainer being compactable to a small size with an almost instantdeployment. A container with a cavity area of approximately 2 foot by 10foot with 11 inch high side walls will compact to a size of 40 inches by48 inches by 3 inches for stowing into a trunk compartment of a smallcar. In a drowning or rescue situation, the compacted and foldedcontainer may be easily accessed and instantly assembled within 3 to 4seconds. As previously described, the containers design does not requirea full assembly or a final interlocking of the hingedly connectedinterlocking flaps to support a person on the water. Further combinedadvantages of the eighth and ninth objects included one prototypetesting with a person being in a first floating container while on thewater and deploying 4 other units from the same first container, andwith each unit having its own attached means of propulsion, or side wallstrengthening flaps. The total time required to deploy the +4 units wasexactly 55 seconds. Other tests included the side wall strengtheningflaps being pre-folded and pre-threaded through the apertures of thesixth object.

It is a tenth object of this invention to alternatively have either oneor both end wall(s), or portions of the walls angled outwardly from thefloor of the container.

An advantage of the tenth object is a container having less resistancewhile on water, and when the container is being propelled in itselongate direction.

It is an eleventh object of this invention to enable a replacement of adamaged hingedly connected interlocking flap via rods connecting acorrugated materials open flute channel apertures, and by forming acorrugated plastic container so that open flute channels are positionedat an upper portion of each distal end wall.

An advantage of the eleventh object is an easy replacement of a damagedhingedly connected interlocking flap via splicing rods which extendthrough flute channels of the interlocking flap, and into the open flutechannels of the end wall. Corrugated plastic is described by amanufacturer as a living hinge; as it will bend repeatedly for tens ofthousands of times without fracturing, but still is not totallyindestructible, and so, in positioning the flute channel openings at theupper edges of each end wall, a replacement hingedly connectedinterlocking flap is attached more easily and more securely by placinginterconnecting rods within the flutes.

It is a twelfth object or goal of this invention; wherein if any partsat all should be added by the manufacturer, they shall add to either thestructural stability of the container as in the fourth, fifth andseventh objects; or they shall add to the speed in assembly as in theeighth object; or they shall add to the containers floatation, and suchas a closed cell floatation foam, or a flute channel plug(s) or rod(s)which shall at least plug one end of an open flute channel to at leastslow a liquids entry; and where any added part may have secondary andalternate functions or results.

In summation; the overall size of this leak proof container is relativeto the need or purpose. The same container design with side wallstrengthening flaps may serve as a food or soup container with aserratingly attached spoon, or to function as an almost instantlyassembled water craft with the serratingly attached side walls servingas a means of propulsion; and with all requiring no assembly tools.

PREFERRED EMBODIMENT

Shown in FIG. 1,a; is a plan view of the preferred embodiment in a flatand unassembled state, and comprising a plurality of bend lines with thesubstrates interior portion, and notched or cut away areas (32) withinthe perimeter edges of the body. A first portions of bend lines (1)parallel the substrate's longest length, and are spaced inwardly todetermine a side walls height. A second portions of bend lines (2)parallel the substrate's shortest length and are distanced inwardly fromthe substrates perimeter edge to define two interlocking flaps (20)which are hingedly connected to the end walls (18). A third portions ofbend lines (3) define the end walls (18) height and are parallel withand located further inwardly than the second portions (2) toperpendicularly nearly abut or abut to conjoin the first portions (1). Afourth portions of bend lines (4) extend inwardly and angularly fromapproximate corner areas to locations where the first (1) and thirdportions (3) nearly abut or abut. The notched areas (12) within theperimeter edges of the two side walls (10) include V-shape notches (12).Two narrow notches (22) are located within each interlocking flap (20).The corner area notches (32) shorten a length of each interlocking flap(20). Shown in FIG. 1,b; are the components of an assembled preferredembodiment, and comprising, two end walls (18), two hingedly connectedinterlocking flaps (20), four exteriorly located hingedly-matedtriangular shape corner flap projections (24), and the floor (34).

Operation

In the forming of a leak proof self securing container which is purposedto contain a human user and or their objects; most any substratematerial may be used, yet one which is repeatably bendable within anyhinge bend line locations will permit a folding and unfolding of thecontainer from and back to a generally flat substrate form for a compactstackability between uses.

The substrate may be of wood or metal which is conjoined withalternative flexible materials forming the hinge bend line portions. Thealternative conjoining materials may comprise rubber or flexible plasticcomposites such as those with a plastic copolymer base that remainflexible in the hinge bend line areas.

Two of the most preferred materials which can be used for the entiresubstrate material including the hinge bend line locations; arepaperboards comprising cardboards or corrugated cardboards in most anyply thickness, and copolymer based plastics. Plastics which arebendable, or those which are heat formed or vacuum formed or injectionmolded will all work fine within this container's design.

When the container is formed in a larger size, and other than whenpurposed as a food container etc., and when purposed to contain a human;and in example, an emergency floating container, it is best formed froma stiffer but still bendable substrate such as a polymer plastic.Unlimited variations and combinations of plastics prevent a completelisting, and so shall not be completely disclosed here; yet one mostpreferred type of plastic substrates is a corrugated plastic beingformed from a copolymer plastic base, and which hereon may be referredto as CP.

To best describe how to construct the container, it shall be elongatewithin at least a few thousandths of an inch to best clarify anddifferentiate its side walls from the end walls, etc.; yet the containermay also be generally square in shape.

FIG. 1,a shows an overhead plan view of the bend lines (1), (2), (3),(4) and cut through notches (12), (22), (32) within the exteriorperimeter edges, and the resulting side walls (10), the end walls (18),and hingedly connected interlocking flaps (20) of the preferredembodiment, while FIG. 1,b shows components of the same, but assembledcontainer.

The substrate in FIG. 1,a is shown in a flat and planar position,wherein a first portion of bend lines (1) parallel the substrate'slongest length, and are spaced inwardly to determine a side walls (10)height. A second portion of bend lines (2) parallel the substrate'sshortest length and are distanced inwardly from the substrates perimeteredge to define two interlocking flaps (20) which are hingedly connectedto the end walls (18). A third portion of bend lines (3) are parallelwith and located further inwardly than the second portions (2) toperpendicularly and nearly abut or abut and conjoin the first portions(1), and to determine the end wall(s) (18) height. A fourth portion ofbend lines (4) extend inwardly and angularly from approximate cornerareas to locations where the first portions (1) and third portions (3)nearly abut or abut. The stated second portions (2) define theinterlocking flaps (20) which include the notches (22) which interlockwith the V-shape notches (12) located in the perimeter edges of thesubstrate, or within the uppermost edge of the side walls (10) of theassembled container in FIG. 1,b to secure each end wall (18) and eachcorner's resulting exteriorly located triangular shape hingedly-matedflap projection (24); wherein each end wall (18) is wedge-locked betweenthe side walls (10) in its assembled position.

After all bend lines and perimeter edge notches are formed as shown inFIG. 1,a, and as an end wall (18) is forced upward and inward to formthe exteriorly located hingedly-mated triangular shape flap projections(24) as shown in FIG. 1,b., the hingedly attached side walls (10) willalso pull inwardly and upward. The projections (24) are locatedexteriorly to the container's cavity area. The user then pushes the endwall's slotted and hingedly connected interlocking flap (20) in adownward direction until the notches (22) interlock with the side wall'sV-shape notches (12). The same process is then repeated at thesubstrate's opposite elongate end. The container is at this point fullyassembled as shown in FIG. 1,b with all four walls being hingedlyconnected to the floor (34), and with each end wall (18) beingwedge-locked between the two side walls (10) and the exteriorly locatedhingedly-mated triangular shape projections (24).

Material surrounding the notches (22) within the interlocking flap (20)additionally prevents the side walls (10) from bending laterally outwardfrom the location of interlocking and also portions of the side wallsbeing near that location.

If the manufacturer insists on adding a part to the part-less container,it might be at this location surrounding the notches (22) of theinterlocking flap (20) with a reinforcement of thin metal or plasticbonding, etc. After numerous interlockings, the substrate may begin toshow signs of wear at this location first, and pending the user's carein assembly, and the material type.

Another method of reinforcing the interlocking flap may include an extrabend extending the longest length of the flap, with portions of the flapfolding back onto itself, and with the notch (22) formed through theextra bending location. Not all possible variations of flapreinforcements are claimed or shown in the drawings, yet are disclosedhere as being obvious by the writer.

Note within FIG. 1,b, the difference in angle between the vertical endwall (18) and the hingedly attached interlocking flap (20). Thisdifference is also seen within FIG. 2,a. Much strength is added to theentire end wall area and side wall areas which are near the end wallswith this flap being hingedly attached to the end wall in this angledform within the assembled container. The difference in angle furtherprevents a lateral twisting of the assembled container, and to at leastsome degree within a partially assembled container.

With a container having a cavity area of 26 inches wide, and 10 feetlong, and with 11 inch high side walls, the entire assembly at a casualpace takes about 15 seconds for 1 person and so with 2 assembly persons,the time taken to walk the feet is eliminated, and the assembly processis reduced from 15 seconds to about 6 seconds.

FIG. 3,a is a perspective view and FIG. 3,b is an overhead view of analternative embodiment of corrugated plastic material, and showinglocations of the substrate's open flute channels (28).

The views within FIGS. 3,a, 3,b, and 3,c are to introduce thealternative embodiment of corrugated plastic. FIG. 3,c is a side viewshowing the interlocking flaps (20) just before they are pushed downwardinto and interlocked with the V-shape notches (12) located within theuppermost edges of the side walls (10).

FIG. 4 is an alternative embodiment representing most any substratematerial with almost all corner areas or sharp edged locations withinthe perimeters edges being chamfered areas (33). Any chamfering in theV-shape notch (12) should be minimal to not defeat its locking grip withthe narrow notches (22) of the interlocking flaps. To retain thedrawings clarity, not all rounded corners are numbered, but remainevident. Also note the nearly abutting bend lines in FIG. 4, (3).

FIG. 5,a is an overhead view of an assembled CP embodiment with all thesame bend line locations of FIG. 4 and chamfered areas (33) surroundingthe interlocking flaps (20). Other components shown are the two sidewalls (10), and the two end walls (18), and two hingedly connectedinterlocking flaps (20), and the four exteriorly located hingedly matedtriangular shape corner projections (24), and one of the open end flutechannel (28) locations, and a direction of the elongate flute channelsbeing represented by a dashed line with double end arrows (30), and thefloor (34).

FIG. 5, b is a side view showing some of the chamfered locations (33) ofFIG. 5,a, and other components including two of the generally V-shapenotches (12) located within the upper edges of a side wall (10), and thetwo interlocking flaps (20), and two exteriorly located hingedly matedtriangular shape corner projections (24).

An alternative shape narrow notch (13) is shown in FIG. 6,a. Notice theslight angle of the notch (13) which is similar in angle to one side ofthe previous V-shape notch (12). The angle of the notch (13), or theV-shape notch (12) within other drawings, depends on the type ofmaterial used, and so may vary according to the manufacturers choice ofease or difficulty in executing the interlocking of the notched flap(20) within the notched portion (13) of the side wall, or for thematerial's strength to retain the interlocking and assembled containersshape.

When an embodiment is extremely elongate as in FIG. 6,a; themanufacturing user may want to incorporate a fifth portion of bend lines(5) which extend the substrate's complete shortest width; and whereinthe container may be folded in half for a more compact storage or easiertransporting, and as shown when folded in half in FIG. 6,b. FIG. 6,aalso shows hand hold aperture locations (37).

When a containers size is 10 to 12 feet long, several bend lines (5) maybe formed as in FIG. 6,c; and with FIGS. 6,d and 6,e showing the stagesof bending and folding the substrate.

As previously described within the objects and advantages section, theweakest point within an extremely long assembled container of 10 to 12foot long will be intermediate its side walls elongate length; and withthe center portions of the walls upper edges not wavering in a directionof their length, but in a slight lateral direction when under pressure.

The alternative embodiment within the overhead plan view of FIG. 7,ashows how a sixth portion of bend lines (6) form side wall strengtheningflaps (14) which are hingedly connected to the side walls. FIG. 7,b is aperspective view of the assembled version of FIG. 7,a; and showing theside wall strengthening flaps (14) being retained within the cavity areaof the container by the interlocking flaps (20). The flaps (20) are heldtightly adjacent the side wall in areas near the notches (22) of theinterlocking flaps (20); yet may bow slightly away from the side wallsin areas where additional support is needed the most; which is in thecenter areas of the elongate side walls, or intermediate their elongatelength.

Any slight bowing does not hinder a side wall's lateral strength, butserves to increase it, as was previously described with added strengthbeing added by the interlocking flap's difference in angle with the endwall's vertical orientation. The described bowing is not shown indrawings, as a type and size of substrate determines if any bowingoccurs at all. Irregardless of whether the strengthening flap (14) inFIG. 7,b completely abuts the attached side wall (10) or not; at leastsome degree of increased side wall lateral stability is still achieved.

FIG. 8 is an overhead plan view of an alternative embodiment utilizing asixth portion (6) of bend lines which define a side wall strengtheningflap, and which is in a shape of a folding paddle (16); and with a lineof apertures (17) which denote a perforated area along the bend line.The apertures (17) only represent intermittent areas within the hingebend line for clarity of the drawing, and may be through cut slitswithin the actual container. A user may choose to remove the paddleshape side wall strengtheners for several other uses, and including afolding of the strengthener to thread through one or more apertures (26)located adjacent an upper edge of the side walls. Aperture (26) uses mayinclude connecting two containers together, or carrying one containervia folded side wall strengtheners, or as a type of oar locks for anemergency paddling situation.

Corrugated plastic is limited in its available width when purchasing insmall quantities, and so FIG. 9 depicts a container with only 1 sidewall strengthening flap to provide for a wider container. FIG. 9 shows asixth portion (6) of bend lines which define a side wall strengtheningflap, and which is in a general shape of a folding paddle (16); and witha line of apertures which denote a perforated or intermittent cutthrough area (17) within the bend line.

Not all possible variations or shapes of side wall strengthening flapsare shown in the drawings, yet are disclosed here as being obvious bythe manufacturer to retain at least some degree of side wallstrengthening, and irregardless of most any shape the flap ismanufactured in.

FIG. 10,a shows only 1 side wall strengthening flap, but with 2 bendlines (6) to define the strengthening flap (14), while also showing astraight end wall (18), and an angled end wall (19). The angle isachieved by moving one of the 3rd portion of bend lines (3) furtherinward than the other 3rd portion (3) from the perimeter edge of thesubstrate.

FIG. 10,b is a side view showing the double bend which provides morestrength through the two bends (6) which define the plural hinge of theside wall's (10) strengthening flap (14).

FIG. 10,c depicts the assembled embodiment of FIG. 10,a. Shown is thestraight end wall (18), the angled end wall (19), two interlocking flaps(20), the locations of the two bend lines (6) which define thestrengthening flap (14) which is hingedly connected to the side wall(10).

FIG. 11 shows a slit formed bend line (2) which opens up two rows offlute channel apertures (28) after the conjoining ribs self score untilreaching the opposite planar wall of the CP material, and will befurther explained in FIG. 19.

FIG. 11 also shows two different methods of threading elastic cords (36)through any apertures (26) or flute channel openings (28). Thisembodiment will self assemble within seconds, and with any finalinterlocking of the flaps remaining as an option to the user, andaccording to the purpose of the container at the time. When the entirecontainer is folded to the configuration of FIG. 6,b, or FIG. 6,e, thecontainer will snap open and assemble itself in about 2 seconds. Anyfinal interlocking of the flaps will require about 3 or 4 seconds perflap.

The elastic cord embodiment in FIG. 11 of an emergency floatingcontainer for a human user and or their objects may be 10 feet long foruse as a water craft, or 18 inches long for use as a toy boat. Withinthe invention's design, size is relative according to the manufacturer'send use purpose. The same 18 inch size container may have uses includinga foot bath, an oil change pan, a tool parts tray, etc.

FIG. 12,a shows an end view of the flute channel openings (28) within anew type of corrugated plastic having a closed cell foam lamination(40), and with FIG. 12,b having a two sided lamination of foam (40).When a container is purposed to be an emergency floating container, thefoam will compensate for any water absorbing non-floating parts such asthe previous elastic cords. The foam material has a secondary functionas a surface protection against dings, etc.

FIG. 13,a and FIG. 13,b are to show the reader how portions of an angledend wall (19) may be accomplished in multiple ways, and that the entireend wall does not have to be angled, but only a portion to reduce anydrag within water, and with the assembled version of FIG. 13,a beingshown in FIG. 13,b.

FIG. 13,a is an overhead plan view of an alternative embodiment withbend portions (7) being slightly curved and still being generallyparallel with the substrates shortest dimension. The drawing is similarto FIG. 4, and shows the first portions (1) of bend lines which parallelthe substrate's longest length, and are spaced inwardly to determine aside walls height. Shown also are a second portion (2) of bend lineswhich parallel the substrate's shortest length, and being spacedinwardly to define the hingedly connected interlocking flaps (20).Notice the seventh portion (7) of bend lines which are curved, yet stillgenerally parallel with and located further inwardly than the secondportions (2), to perpendicularly and nearly abut or to abut and conjointhe first portions (1). Shown also are a fourth portion (4) of bendlines which extend inwardly and angularly from the substrate's cornerareas to a location where the first and seventh portions (7) abut ornearly abut. Shown also are locations of a generally V-shape notch (12)within the side walls (10). Shown also are locations of a narrow notch(22) within the end walls (18) interlocking flaps (20). Also shown aretwo angled portions (19) of the end walls. Note that a part of thecutaway portions (32) within the flat substrates corner areas is toshorten a length of the interlocking flap. Shown also are several areasof chamfering (33). To retain the drawings clarity, not all roundedcorners are numbered, but remain evident.

FIG. 13,b is a perspective view from one elongate end of the assembledcontainer of FIG. 13,a. Shown are two end walls (18), and two portionsof the end walls which are angled portions (19), and four locations ofcurved bend lines (7), and two side walls (10), and four hingedly-matedtriangular shape projections (24), and the floor (34). The side wallnotches and interlocking flaps are not included in this drawing for abetter view of the angled portions.

The slit formed hinged interlocking flap is the second foremost sourceof strength after the wedge-locked end walls and the exteriorly locatedhingedly mated corner projections, and either if the interlocking flapis originally and hingedly attached to the end wall, or whether it isoffered by the manufacturer as a separate unit to be installed by theend user as shown in FIG. 14,d.

FIG. 14,a shows one end wall (18) with a damaged interlocking flapremoved or completely cut off at the hinge line, and with a replacementinterlocking flap (20) being shown in FIG. 14,b, and with a slit formedhinge bend line (2) and an extended portion (21) and its positioningshown in FIG. 14,c, and with any connecting rods (39) shown in FIG.14,c. Connecting rods may be of any shape other than those shown, andmay be injection molded to more precisely match the shape of a flutechannel. A replacement connecting flap only applies to a CP containerwith open flute channels at each elongate end, and may include theconnecting rods being pre-attached within the extended portions (21).

One method of reinforcing the material surrounding the notch (22) withinan interlocking flap (20) is shown in FIG. 15,a and b; where plan viewsshow a doubling up of corrugated material surrounding a notch (22) of aninterlocking flap (20) before and after the material has been foldedover onto itself. FIG. 15,c shows a side view of FIG. 15,b where thenotch is cut through two layers of substrate. Also note the generallycircular shape notch (15) within the side walls (10) of FIG. 15,a andFIG. 15,b.

Just as the corrugated plastic embodiment has multiple and additionalfunctional properties within its existing form; and comparatively as theclosed cell laminated foam embodiment comprises further propertiesbeyond floatation, and such as a surface protective material; a flutechannel plug (44) in FIG. 16 also has a secondary function as a means toattach a flap (20) within a side wall notch (12).

When any shape of flute channel plug (44), (46), (48) is inserted withinboth opposite ends of an open flute channel of a corrugated plasticcontainer, a closed and buoyant floatation cell is formed. When a plugis inserted into only one end of any flute channel, a certain amount ofair may be trapped within the channel as the substrate is eitherfloating on a waters surface, or swept under the surface; and so atleast aids or at least has the potential to aid in a containersfloatation. All plugs are preferably formed of a material such as woodor air impregnated plastic to not reduce the containers floatationproperties, yet may be of most any material substrate and may beinserted anywhere in the container, and may also have the previouslydescribed secondary function as a means of attachment between aninterlocking flap and a side walls notch.

FIG. 16 shows an overhead view of a corrugated plastic substratecontainer being similar to FIG. 3,b, but including rod like flutechannel plugs (44), and with no interlocking flap notch locations. Alsoshown are end walls (18), the side walls (10), the interlocking flaps(20), the floor (34), various locations of flute channel openings (28),and with flute channels that have been opened via bend lines formed viaa hinge forming slit (2), and also showing the direction of the elongateflute channels (30). The air trapping rod-like plugs (44) shown may bepartially inserted into any flute channels of the interlocking flaps(20) to surround and laterally retain the side walls (10) within thenotched area, and so eliminates a need for a notch within theinterlocking flap. Most plugs may also be used to reinforce the materialsurrounding a notch within a corrugated interlocking flap; yet are notall shown.

FIG. 17; A perspective end view of an interlocking flap (20) having onlyone notch (22) location to receive a generally W-shape flute channelplug (48). The outer portions of the W-shape are inserted into flutechannels surrounding the notch (22), and the centered apex portion ofthe W-shape is located within the notch. The drawing also shows anH-shape flute channel plug (46) which eliminates the need for formingany notch (22) within the interlocking flap (20).

Notice all the retained angles between the multiple planar surfaces ofthe substrate within FIG. 18. A perspective side view is shown of anunassembled embodiment after it was pre-bent or assembled at least once,and as if it were on a waters surface (50) with a human user in thecavity area, but with the human not shown, and showing all bend linelocations (1),(2),(3),(4). Shown also are the two flaps (20) which arehingedly connected to the end walls (18). The difference in planarangles of all surfaces prevent a lateral twisting of the substrate whenon a waters surface. In this embodiment, the hingedly connected slitformed flaps (20) will especially aid to prevent lateral twisting of thecontainer near each distal end.

This retained form of a rectangular saucer-like shape is especially dueto the method in which the interlocking flap defining slit formed bendlines (2) were formed in the corrugated plastic substrate.

If these bends were crimped bends, the membrane wall being exterior tothe bend line would need to stretch a much further distance than theinterior wall surface of the bend line, and so would result in a lesserdegree of any angles, or a more floppy and less stable form near eachdistal end of the container.

Shown also in FIG. 18 are two side walls (10) which are hingedlyconnected to the floor (34) via slit formed bends (1), and the floor(34) being hingedly connected to the end walls (18) via slit formedbends (3).

The unassembled container of FIG. 18 which retains its partiallyassembled form upon a waters surface enables a swimming user or acontainer retained user to guide only the two side walls inwardly andupwardly for the containers assembly.

Many prototype tests made in a small but fast flowing river haveincluded persons jumping from the shoreline and onto the unassembledcontainer, and remaining afloat to pull only the two side walls upward,and wherein the persons weight load combined with the waters upwardpressure caused all walls to be shifted inward and upward, and with thefour triangular shape projections shifting outwardly for the containersassembly. This embodiment was manufactured by forming all hinge bendlines with slits made on only one side of the CP material.

As previously described, a corrugated plastic substrate has two planarwalls which are conjoined by elongate paralleling ribs. When one planarwall is slit with a hand held cutting tool, a controlled depth sawblade, or a CNC cutting machine, the internal ribs between the two wallsupon bending the substrate, will self score until the slit reaches theopposite planar wall, which will then function as a hinge bend line. Itis this method of forming a hinge bend line which best enables thesubstrate to more so retain a partial shape of any previous bends, andcombined with the memory retension of the plastic substrate. Bend lineswhich parallel any flute channels can be either crimped or slit formed,but material surrounding slit or slot or notch formed bend lines whichare perpendicular to the elongate flute channels are more easily bent,and will retain a straighter and more accurate bend line location.

Material within a slot formed bend line will self score upon bending asubstrate similarly to a slit formed bend line. Material surrounding analigned plurality of notched apertures or a notch formed bend line willstretch in a direction toward the bend line, and is not as easily bent,but will retain an accurate location.

Within the three methods described for forming any bend lines, oneadditional advantage is in the manufacturing of any larger sizecontainer, and such as one using an initial 4 foot by 12 foot by ½ inchthick corrugated plastic material. Large bending equipment is not neededto form any bends within the semi rigid material.

The elimination of large, and so, very expensive bending equipment mayfar outweigh any previously described goals of the invention within theprevious objects and advantages portion of this disclosure. If selectedslit or slot formed hinge bend lines are somewhat intermittent in theircontinuity, and or do not extend completely to an edge of the CPmaterial, the substrate will retain a more rigid and planar form untilthe end user makes any initial bends. Shipping and handling will beeasier when transporting a more rigid and planar substrate, and sodollar costs of transport and handling should also be reduced.

FIG. 19 shows a perspective view of various hinge bend lines within acorrugated plastic embodiment; and showing a slit formed bend line (52),and a slit forming tool (53) example; and a slot formed bend line (54)location, and a slot forming tool (55) example; and a notch formed bendline (56), and a zoomed in view of a notch shape (57). Also shown is aplanar membrane wall (58) within the corrugated material, and aconjoining rib (60) within the corrugated material, and one of manyflute channel openings (28). A final size or end use purpose of thecontainer will determine the manufacturers choice of which type of hingebend line forming tool is best.

CONCLUSION, RAMIFICATIONS, AND SCOPE

In summation, a means of attachment of the hingedly attachedinterlocking flap to the notches within the side walls may not require anarrow notch within the interlocking flap, as some means disclosed inthe drawings eliminate a need for the narrow slot like notch within theinterlocking flap. The notches within the side walls are a necessaryelement for a good lateral securement of the side walls for a containerwhich requires no parts; yet it shall be deemed as an obviousness thatan almost unlimited number of means to attach the hinged interlockingflap to the side walls does exist, and where this disclosure does notattempt to disclose all.

The foremost asset of the assembled container is its lateral wallstrength, and especially in an extremely elongate form, and whileremaining substantially leak proof, it retains opposingly stressedelements which produce a secure wedge-locked strength near and at eachend wall location. The side wall strengthening flaps complete itsstrength nearly to the equivalent of a six sided box; and yet with allbeing formed from a single planar substrate which requires no parts, orglues, or tapes, or staples, or tabs, or tab receiving apertures, orassembly tools.

It should be understood by the reader that this new concept of a leakproof self securing container for a human user and or their objectsentails many diverse uses; and wherein the end uses cannot all bedisclosed, yet should be addressed to inform or remind the reader thatas previously stated, size is relative to the final intended purpose;and wherein any purposes to be absolutely leak proof or the degree towhich the container is to be leak proof is also according to a type ofmaterial substrate a manufacturer chooses to form the container from.

Any paperboard embodiments of the leak proof container may includevarious coatings of oils, waxes, or plasticizers or other water proofingsprays, or immersions to further a container's leak proof properties.And similarly, any plastic embodiment may include buoyant coatings ofclosed cell foam or in combination with air impregnated plastic portionsin locations of the entire substrate or portions of the substrate. Allplastic types are not claimed, as it shall be understood that most anycombination of plastic polymers from the hundreds which exist; willfunction fine.

And just as a manufacturer's chosen size of the leak proof containerwill determine whether a 200 lb. or a 400 lb. person may use thecontainer as a water craft; a smaller size leak proof container mayalternately serve as a toy boat or floating tackle box.

The side wall strengthening flaps are of great value when in specificshapes such as a folding paddle blade. When combined with the bend lines(5) a store display may exhibit dozens of container type emergency watercrafts with an attached means of propulsion being stacked on a singlepallet.

It is understood that various end uses of any invention can not alwaysbe claimable; and yet when a disclosure such as this has so manymultiple and purposed uses in an emergency flood situation, and aspreviously described in application Ser. No. 11/288,463, the overallvalue of the invention changes via the greater synergistic effect of thecombined end uses.

Although previous descriptions contain many specifics, these should notbe construed as limiting the scope of the invention but as merelyproviding illustrations of some of the several presently preferredembodiments of this invention of a leak proof self securing containerfrom a single sheet; and wherein a similar container may be of analuminum or wood or plastic substrate having flexible hinge bend linesof a different material which are adhered or vulcanized or heat meltedto the substrate in locations adjacent or surrounding the bend lines.

And in conclusion, the photograph converted to copyable line art in FIG.20 depicts 2 passengers within the 10 mil or ½ inch thick walled opencontainer type emergency water craft, and while on the waters surface,and while using the side wall strengthening flaps as a means ofpropulsion, and with no other parts being used as shown in the plan viewdrawing of FIG. 8 which shows only 1 substrate sheet. The photo wascaptured as one frame from a low resolution video device; and so is arough line art rendition, yet is self evident in describing thepreceding disclosures and merits of a leak proof self securing containerfrom a single sheet, and which requires no additional parts.
